Surface-enhanced Raman spectroscopy of cell lysates mixed with silver nanoparticles for tumor classification
The throughput of spontaneous Raman spectroscopy techniques for cell identification is limited due to the relatively low sensitivity and long acquisition time. This throughput can be increased by surface...
PublicationsDiscrete tuning concept for fiber-integrated lasers based on tailored FBG arrays and a theta cavity layout
e demonstrate a novel tuning concept for pulsed fiber-integrated lasers with a fiber Bragg grating (FBG) array as discrete and tailored spectral filter as well as a modified laser design. Based on a theta...
PublicationsDual-focus coherent anti-Stokes Raman scattering microscopy using a compact two-beam fiber laser source
We have developed a dual-focus coherent anti-Stokes Raman scattering (CARS) microscope based on a dual output, compact fiber laser source. The underlying concepts of time-multiplexed, two-beam scanning...
PublicationsNanoboomerang-based inverse metasurfaces – a promising path towards ultrathin photonic devices for transmission operation
Metasurfaces have revolutionized photonics due to their ability to shape phase fronts as requested and to tune beam directionality using nanoscale metallic or dielectric scatterers. Here we reveal that...
PublicationsSelf-healing polymer networks based on reversible michael addition reactions
A new polymeric material utilizing a highly efficient as well as reversible thiol-ene click reaction is presented. For this purpose, a trithiol is reacted with a bisbenzylcyanoacetamide derivative resulting...
PublicationsElectromagnetic wave propagation through air-core waveguide with metamaterial cladding
Metamaterial-based waveguides offer unusual properties compared to conventional metallic and dielectric waveguides. We experimentally investigate a novel waveguide with an air-core and a cladding formed...
PublicationsBridging the gap between the mesoscopic 2D order–order transition and molecular-level reorganization in dot-patterned block copolymer monolayers
Langmuir-Blodgett (LB) films of amphiphilic block copolymers (BCs) form well-defined nanostructures with long-range order useful, for instance, for nanolithography applications. Nanostructures with a 2D...
PublicationsPeriodic array-based substrates for surface-enhanced infrared spectroscopy
At the beginning of the 1980s first reports of surface enhanced infrared spectroscopy (SEIRS) surfaced. Probably due to enhancement factors of only 101 to 103, which are modest compared to those of surface...
PublicationsAutarke Energiequellen und optische Sensoren für Smart Flexibles
In dem Beitrag wird aufgezeigt, dass Solarzellenbeschichtungen auf Folien und Geweben sich für energieautarke Smart Flexibles eignen. Ein innovatives und patentiertes Verschaltungskonzept für Solarzellen...
PublicationsA microwave photon detector
The possibility of the implementation of a single-photon detector in the microwave range has been discussed. It has been shown that, for these purposes, it is possible to use an unshunted Josephson junction,...
